All personnel aboard a US military helicopter carrying American service members were killed in a crash in western Iraq, the US Central Command says.
Central Command did not say how many people were killed in the crash late on Thursday. A US military official told Reuters the US HH-60 Pave Hawk helicopter was carrying seven people.
The crash, which did not appear to be the result of enemy activity, is under investigation, the command said in a statement on Friday.
"All personnel aboard were killed in the crash," said Brigadier General Jonathan P. Braga, director of operations of the Combined Joint Task Force. "This tragedy reminds us of the risks our men and women face every day in service of our nations."
The military said a second accompanying American helicopter immediately reported the crash and Iraqi security forces and coalition members secured the area.
Two US officials, speaking on condition of anonymity and citing initial reports, said on Thursday the aircraft crashed near al-Qaim, a town in Anbar province close to the Syrian border.
The US says it has about 5200 troops in Iraq that are part of a coalition fighting Islamic State militants.
